I had a hard time thinking of somebody. I put Alex Lifeson from Rush. I say Alex because he tended to be overshadows by Neil's ridiculous drum skills and Geddy's bass. Since had had to do double duty as a lead and rhythm guitarist, couldn't just let 'er rip and was overshadowed by the hair metal shredders of the 80's. Stuff like "Red Sector A", with its awesome chord and rhythmic work, didn't stand out amongst the shredders of the time.

Somebody posted Mike McCready from Pearl Jam (and Mad Season). After watching a Mad Season live video, I have to agree :-).
